return success).

ba39702411 ip_fwdef.c was missing some assignments , and this 
caused that bug by which firewall code was not working
if configured into kernel and worked only as lkm.
Now this must be fixed...Sorry guys..

07d192a9fb Change caching strategy somewhat: 
1) Don't clone routes to multicast destinations; there is nothing useful
   to be gained in this case.
2) Reduce default expiration timer to one hour.  Busy sites will still
   likely want to reduce this, but for ordinary users this is a reasonable
   value to use.

dd3cca2bda Actual firewall change. 
1) Firewall is not subdivided on forwarding / blocking chains
   anymore.Actually only one chain left-it was the blocking one.
2) LKM support.ip_fwdef.c is function pointers definition and
goes into kernel along with all INET stuff.

ffabe2a5ad Fix a bug which caused panics when attempting to change just the flags of 
a route.  (This still doesn't work, but it doesn't panic now.)  It looks
like there may be a number of incipient bugs in this code.

Also, get ready for the time when all IP gateway routes are cloning, which
is necessary to keep proper TCP statistics.

9ce9e24f39 Implement full proxy ARP, gated on option ARP_PROXYALL. This allows 
a FreeBSD box to do proxy ARP as easily as most commercial routers do,
without messing around with (potentially variable) Ethernet addresses.
This code is really quite simple; I'm not at all sure why it wasn't
implemented in 4.4.

It might be worth stealing an interface flag (maybe IFF_LINK1) to use for
finer-grained control over which interfaces get proxy treatment.  For the
moment, it's all or nothing.
